NAME

       lpsinvelm - check invariants and use these to simplify or eliminate summands of an LPS

SYNOPSIS

       lpsinvelm [OPTION]... --invfile=INVFILE [INFILE [OUTFILE]]

DESCRIPTION

       Checks  whether  the  boolean  formula (an mCRL2 data expression of sort Bool) provided as
       invariant is an invariant of the linear process specification (LPS) in INFILE. If this  is
       the  case,  the  tool  eliminates  all  summands  of  the LPS whose condition violates the
       invariant, and writes the result to OUTFILE. If INFILE  is  present,  stdin  is  used.  If
       OUTFILE is not present, stdout is used.

       The tool can also be used to simplify the conditions of the summands of the given LPS.

OPTIONS

       OPTION can be any of the following:

       -y, --all-violations
              do  not  terminate  as  soon  as  a single violation of the invariant is found, but
              report all violations instead

       -c, --counter-example
              display a valuation indicating why the invariant could possibly be violated  if  it
              is uncertain whether a summand violates the invariant

       -o, --induction
              apply induction on lists

       -iINVFILE, --invariant=INVFILE
              use  the  boolean  formula  (an  mCRL2  data expression of sort Bool) in INVFILE as
              invariant

       -n, --no-check
              do not check if the invariant holds before eliminating unreachable summands

       -e, --no-elimination
              do not eliminate or simplify summands, but add the invariant to each condition

       -pPREFIX, --print-dot=PREFIX
              save a .dot file of the resulting BDD if it is impossible to  determine  whether  a
              summand violates the invariant; PREFIX will be used as prefix of the output files

       -QNUM, --qlimit=NUM
              limit  enumeration  of  quantifiers  to NUM variables. (Default NUM=1000, NUM=0 for
              unlimited).

       -rNAME, --rewriter=NAME
              use rewrite strategy NAME: 'jitty'  jitty  rewriting  (default)  'jittyc'  compiled
              jitty rewriting 'jittyp' jitty rewriting with prover

       -l, --simplify-all
              simplify  the  conditions of all summands, instead of just eliminating the summands
              whose conditions in conjunction with the invariant are contradictions

       -zSOLVER, --smt-solver=SOLVER
              use SOLVER to remove inconsistent paths from the internally used BDDs (by  default,
              no path elimination is applied): 'cvc' the SMT solver CVC3

       -sNUM, --summand=NUM
              eliminate or simplify the summand with number NUM only

       -tLIMIT, --time-limit=LIMIT
              spend at most LIMIT seconds on proving a single formula

       --timings[=FILE]
              append  timing  measurements to FILE. Measurements are written to standard error if
              no FILE is provided

       Standard options:

       -q, --quiet
              do not display warning messages

       -v, --verbose
              display short intermediate messages

       -d, --debug
              display detailed intermediate messages

       --log-level=LEVEL
              display intermediate messages up to and including level

       -h, --help
              display help information

       --version
              display version information
